This is caused by changing the price types or registration options on the event while the event is live on the web. Follow the steps below to resolve the issue:

Go to Sales > Unresolved Online Sales Order.

Open the Order.

Click on View Unresolved Online Order Error. See error: The record specified does not exist for this data form.

Look in the cart on the right hand side of the screen. See that a price type or a registration option is missing, but the event name is listed.

Highlight the item and delete it out of the cart.

Go to the Create Order tab and add the same event item back into the cart, but with the correct price type.
